Square Pyramid formulas
| $$ V = \frac{a^2 \, h }{3} $$ |
| volume |
| $$ A_{base} = a^2 $$ |
| base area |
| $$ A_{lat} = 2 \times a \times h $$ |
| lateral area |
| $$ A_{tot} = A_{base} + A_{lateral} $$ |
| total area |
| $$ r = \frac{a}{2} $$ |
| base radius |
| $$ s^2 = h^2 + \frac{a^2}{4} $$ |
| slant height |
| $$ e^2 = s^2 + \frac{a^2}{4} $$ |
| lateral edge |
| $$ e^2 = h^2 + \frac{d^2}{4} $$ |
